Solution Overview

Problem

Inadvertent selection issues arise when using touch-sensitive interfaces on screens that change rapidly during content construction, leading to false triggering of links as the user's touch point does not align with the moved link position, causing unintended website access or missed selections.

Innovation Solution

Displaying provisional content at a temporary position with selection options, recognizing selections at this position, and transitioning to final content display without delaying the page build-up, allowing for accurate selection by maintaining the initial touch point's validity during screen content changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the screen content is updated rapidly during page build-up, then the content is displayed quickly, but the link position changes cause false triggering of selections

Engineering Contradiction:
Improvepage build-up speedVSAvoidselection accuracy
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system displays a provisional placeholder at the expected link position before the actual content is ready. This preliminary action allows the user to interact with the link at its final position even though the content hasn't fully loaded yet, preventing false triggering while maintaining fast display performance

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

A provisional link element acts as an intermediary between the user's touch input and the actual link content. This intermediary element occupies the final link position during page build-up, allowing accurate selection recognition without requiring the full content to be loaded first

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If a delay is introduced to allow content to load before display, then selection accuracy improves, but the page build-up time increases

Engineering Contradiction:
Improveselection accuracyVSAvoidpage build-up time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

Instead of delaying the display, the system performs preliminary action by showing placeholder elements at the correct final positions. This allows selection recognition to proceed immediately without waiting for content loading, eliminating the time loss while maintaining accuracy

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The page build-up process is segmented into independent elements. Each link element can be individually positioned and made selectable without requiring the entire page content to be loaded, allowing parallel processing and reducing overall build-up time

Inventive Principle:
Principle #1Segmentation

AI summary

The invention relates to a method and a device for providing a selection possibility (13, 14, 15) while producing display content on a display surface (11) of a display device (10) and to a display device (10). The invention further relates to a vehicle with an installed display device. The method includes a step of displaying preliminary display content at a preliminary position on the display surface (11), said display content having at least one selection possibility (13, 14, 15). The method further has the steps of detecting a selection of at least one of the selection possibilities (13, 14, 15) at the preliminary position of the display surface (11) and displaying final display content at a final position on the display surface (11). Furthermore, the selection of at least one of the selection possibilities (13, 14, 15) at the preliminary position is detected as a selection while the final display content is already displayed at the final position on the display surface (11).
